Excluding Protozoa, nearly 100 specimens of invertebrates and fishes were obtained 
in these trawlings, belonging to 35 species, of which 25 are new to science, including 
representatives of 9 new genera ; 13 of the new species and 3 new genera were not 
obtained elsewhere. 
Willemoes-8uhm writes : “ The Philippines are rich in Cirripedia, having not less than 
eighteen species ; to-day we took two, one on a Cidaris and one on the queer shell of a 
P/'orus. One of the Crustacea was a fine normal Ncphrops distinguished by the shortness 
of its antennal scale.” 
Surface Orga n is m s. — The following species are recorded from the surface (November 
2 and 3) : — 
Titniuata (Herdman, Zool. pt. 76). Fishes (Gunther, Zool. pt. 78). 
Pyrosoma yiyanteum, Lesueur (?). Scopelus caninianus (C.V.), (young). 
In addition, the following are recorded in the note-books : — A few Diatoms, Vorticella 
on Diatoms, Pcridinium, Pyrocystis, Oscillatoriacege, Globig&nna, Orbulina, Pulvinulina, 
Radiol. i ria, larva of Navtactis, Medusae and eight-armed larva ( Cyanea ), Diphyes and 
other Siphonophorse, Echinoderm larvae, Pluteus, Sagitta, Alciopa, larvae of Terebellids, 
8a be 11 ids, and Aphroditaceans, Pilidium, many Copepods ( Copilia , Corycseus, &c.), 
Oxycephalus, Crustacean larvae, larval Lamellibranchs, Cardiopoda, Hyalasa 
[ = Cavolinia}, Cymbulia (from the trawl), Pteropod larvae, Appendicularia, small 
Salpa . FritUlaria, young Amphioxus. 
W illemoes-Suhm writes: “The trawl caught a Cymbulia on the surface, three species 
of which arc known from the Mediterranean and one from the Pacific. As far as I am 
aware we have never taken it alive, and only once (at Gibraltar) a dead shell was picked 
up by Murray on the beach.” 
The Challenger anchored at Manila at 2.30 p.m. on November 4, remaining there till 
2 p.m. on November 11, 1874. 
Surface Organisms. — The water in Manila Harbour generally looked very muddy, 
and contained a good deal of fine mud apparently from the river. There were also many 
small gr-en masses, probably an Alga ( llalosphsera). There were many Diatoms of 
different pecies, one of which (Bacteidastrum ?) was nearly always crowded with 
VortlcelUf, while none were noticed on any of the other species. Several kinds of 
Infusoria woi< ob rved, and very many specimens of Peridinivm (Peridimum tripos 
and two other species), alone' with Pyrocystis and Noctiluca. Noctiluca had evidently 
l>c« n feeding on Diatoms and other mall organisms, as these were frequently found
